The Momentix Co-Inventor Kit provides the key connecting pieces (like levers, pulleys, and ramps) to make chain reaciton machines while introducing kids to the engineering design process. 


This limited edition of our kit gives kids the special opportunity to co-invent the next generation of our toys with us by sharing their opinion. Kids who participate in the co-inventing process will receive a Toy Inventor certificate!


The kit comes with enough pieces to make 3-4 mechanisms simaltaneously. In classrooms, up to 3-4 kids can work collaboratively to learn the invention process using one Momentix kit.
